What is used to treat Persistent pulmonary hypertension of the newborn?

Inhaled corticosteroids
Intravenous fluids
Inhaled NO
Oral antibiotics

The correct answer is: Inhaled NO

Persistent pulmonary hypertension of the newborn is a condition where the blood vessels in the lungs do not fully relax after birth, leading to low oxygen levels in the body. In order to treat this condition, medications that help relax the blood vessels are often prescribed. Inhaled corticosteroids, intravenous fluids, and oral antibiotics do not address the underlying issue of constricted blood vessels in the lungs. Inhaled NO, or nitrous oxide, specifically targets and relaxes the blood vessels in the lungs, making it the most effective treatment for persistent pulmonary hypertension of the newborn.
